'79 Raleigh Competition G.S. build (650b..)
Picked up this rough '79 Comp GS in January. I've been going back and forth about what to do with it, finally decided to build it up as a 650b conversion with some parts from the bin & some parts 'borrowed' from other bikes.
Before-
Today on it's shake-down ride-
I'd like to figure out how to make the Campy GS stuff work (I love the aesthetics of the 3-arm crankset....), though I'm not sure it'll be possible. And if there's a better friction-shifting experience than Retrofriction levers moving Suntour Cyclone mechs, I've never had it! I wasn't really sure what to expect- the test ride in the rain when I bought it, with old, flabby tires, hardened grease, rusty chain, etc. didn't tell me much. But wow- it's quite nice. Quick, responsive, but also stable and comfortable. This drivetrain will have to go back to the bike it was borrowed from, so I'll have to figure out what to do here.

I just sold mine . I only sold it because it was a bit small. My 1977 was all original and in very good condition with the original GS mech. I changed the rear derailleur after the cage came apart. I was able to repair it but the Nuovo Record worked well and I left that on the bike. It looks like your Cyclone will allow for better gearing choices , I would leave it or find an equivalent.These are very responsive and light bicycles. I had many happy miles over about 8 years . I’m not sure , other than the 650 conversion , how you got those wider tires on . I was running 700 x 23 but probably could’ve fit 25’s easily. Joe

That's a nice build!
Looks like you're running Gran Bois Hetres - kudos for mounting them with the label aligned with the valve stem. The Competition GS chainstays were typically a bit shorter than the Competition model. I see you've got the wheels all the way back in the dropouts. How much clearance do you have?

Nicely done! My very first 650b conversion was a Competition GS. I ran it with Col de la vie 38mm tires (this is before Hetres appeared, iirc) and a Campy NR rear mech shifting a 32t large rear cog! I had to remove the dropout adjusters and pull the wheel as far back as it could go. I’ll dig up some pics.

This drivetrain (temporarily borrowed from my Holdsworth), 46/42 x 13-32, I can just get away with in my steep and hilly terrain, though there are a couple particularly tough climbs I avoid. I've got a 49D compact double I might try, once I figure out (and find..) the right BB spindle for it, but then I lose the 1/2-step gearing I really love. I've also been oogling the Stronglight Tevano triple- a nice looking Campy knock-off that seems easier to find in a triple than an actual Campy triple... If the right rings existed for the Gran Sport three-arm crank, I'd consider drilling & tapping to make it a triple (yeah, potentially risky, I know).

Nice build man! Been riding my Triumph Gran Course 650b conversion lately. (Raleigh Professional sort of). Anyway, quick geometry and 650b is a hoot. Who knew 67 year old kids could have this much fun!

Had these fenders lying around from a dismantled build- re-radiused from 700 to 650, a little narrow for 42c tires, but they'll do for now (until V-O has a sale.....). Generally prefer silver fenders, but the black actually looks OK on this. A parts-bin mish-mash build, but it rides very nicely.

Beautiful build! I'm starting to go down the rabbit hole of 650b conversions/randonneuring builds. What does your chainstay dimpling setup look like?

Neck/shoulder issues have me giving upright bars a try. I miss the multiple hand positions- if I stay with upright I think I'll try some mustache bars. Reaching down to the shifters from upright is kind of a pain, so bar-ends would be part of the picture. Or.... I might go back to the drop bars and a taller stem.....

Before you go back to drops, try Albatross bars. I’ve had them on a couple of builds, and they’re great. You have the grip area, but I end up on the fronts of the bars for climbs, and they’re wide enough to easily tuck from the grips on descents while keeping my hands hovering over the brakes. I love em.

A little crude, but it does the job. I can't remember exactly what I fashioned the bit on the end of the clamp from- I think maybe it was a large bolt that I took a grinder to. Ideally it would be spot welded to the clamp, but it's just epoxied on there, and it's held so far. Others do the dimpling vertically, but from what I've read horizontally is less likely to negatively impact the integrity/strength of the tubing.

They also take bar end shifters with regular upright brake levers — what’s not to like? I’ll wrap these up for you and ring you up at this register over here.

Ha, I just put the drops back on! But it was quick and easy as I had left the stem/bars/levers/cables/wrap all together when I took ‘em off. I did a decently long ride with a pal this AM on my PX10, and just thought there’s no way I could do this on the GS with the limited position options with the All Rounder bars…. But I do think I am going to get some Albatross bars to try. Neck felt/feels fine today after the PX10 with drops, but it’s an up-&-down, day-to-day issue.
